• How to remove previous versions of Xcode

  - by Ed Marty

  When the 3.2 beta of the iPhone OS first came out, Xcode for 3.2 had to be installed side-by-side with the version for 3.1.2. I installed the new version (3.2) in /Developer and moved 3.1.2 to /Xcode3.1.2. Now I want to get rid of the old version and just use the new one since we can do that now. I ran the uninstall tool at /Xcode3.1.2/Library/uninstall-devtools and uninstall-developer-folder, but the directory still exists and has lots of stuff still in it, adding up to about 5 GB. At this point, am I safe just deleting the folder if I want to totally get rid of it and still use the /Developer folder? (At about 8 GB, it's got lots more in it, but I'm not sure if that's just because it's larger or because the old version was 8 GB before I ran the uninstall tool)?

• Prevent bot from crawling certain areas of site.

  - by Skoder

  Hey, I don't know much about SEO and how web spiders work, so forgive my ignorance here. I'm creating a site (using ASP.NET-MVC) which has areas that displays information retrieved from the database. The data is unique to the user, so there's no real server-side output caching going on. However, since the data can contain things the user may not wish to have displayed from search engine results, I'd like to prevent any spiders from accessing the search results page. Are there any special actions I should take to ensure that the search result directory isn't crawled? Also, would a spider even crawl a page that's dynamically generated and would any actions preventing certain directories being search mess up my search engine rankings? edit: I should add, I'm reading up on robots.txt protocol, but it relies on co-operation from the web crawler. However, I'd also like to prevent any data-mining users who will ignore the robots.txt file. I appreciate any help!

• Perl file test operator help

  - by Aaron Moodie

  This is a really basic issue, but I'm new to perl and cannot work out what the issue is. I'm just trying to isolate the files in a directory, but the -d operator keeps treating all the folder contents as files ... @contents is my array, and when I run this: foreach $item(@contents) { if (-d $item) { next; } print"$item is a file\n"; } I keep getting both folders and files. Alternatively, if I use -f, I get nothing. edit: this is the output - file01.txt is a file folder 01 is a file folder 02 is a file Screen shot 2010-04-18 at 1.26.17 PM.png is a file I'm running this on OSX

• Create javadoc with multiple src dirs

  - by Ed Marty

  I have a Util package with source files in three seperate directories, defined like so: src/com/domain/util src/Standard/com/domain/util src/Extended/com/domain/util The package is built with the first set of files and either one of the second or third set, to create a total of two different implementations of the same interface. Now, I want to generate javadoc based on those files. How can I specify that? What I really want to do is javadoc com.domain.util -sourcepath ./src;./src/Standard to build the javadoc for the standard util package, and javadoc com.domain.util -sourcepath ./src;./src/Extended to build the javadoc for the extended util package. This doesn't work. The only way I've found so far to actually make it work is to merge the directory structure of the common classes and the Standard classes into another location and run with that for the standard javadoc, then do the same for the Extended package. Is there another way?

• Problem with Apache Commons Id UUID Version 1 generation

  - by Pekka Mattila

  My problem is to generate version 1 UUIDs. We use Jetty 6.x, Maven (to start Jetty among other things) and Apache Commons ID (to generate UUID version 1 from the current time). Apache Commons ID requires a configuration file that is told to the JVM, using a parameter, e.g. 'org.apache.commons.id.uuid.config.resource.filename=commons-id-uuid.xml'. I checked the Apache Commons ID code and it tries to find the file from the classpath. Jetty's documentation states that WEB-INF/lib and WEB-INF/classes are in the classpath. The 'commons-id-uuid.xml' can be found from the deployed war file from the root of WEB-INF/classes directory but Jetty cannot load it: Message: java.lang.RuntimeException: java.lang.IllegalStateException: commons-id-uuid.xml loaded as system resource is null Jetty was started using the following command: mvn jetty:run -Dorg.apache.commons.id.uuid.config.resource.filename=commons-id-uuid.xml Any idea what is going wrong? We just need to generate UUID version 1 identifiers. Any suggestions?

• Extending Ruby, calling a function from C

  - by ThePower

  Hi, I'm writing an app that calls ruby code from c. I am having a little difficulty and wondered if anyone could point me in the rite direction. I currently have in my C. #include ruby.h main() { ruby_init(); rb_require("myRubyFile"); rb_funcall(rb_module_new(), rb_intern("RubyFunction"), 0, NULL); } My ruby file is in the same directory as my c file and is called myRubyFile.rb and contains a definition of the function RubyFunction(). This is a cut down of what I actually want to do, just making it more readable for others. I just require some feedback as to whether this is the correct method to call ruby code from my c file. Regards

• VIsual Studio and Ajax Control Toolkit

  - by Steve

  In my web application VS 2008 solution, I have the AjaxControlToolkit.dll in my bin directory and a whole set of language directories for it (ar, cs, de,es, fr, he, etc...) I don't remember how the language directories got in there. If I am using other languages via the ACT, do I need these directories? If not, then I don't? When I do a rebuild solution, the dll (AjaxControlToolkit.resources.dll) in these directories disappear. If I need them, what do I need to do to keep them from being deleted during a rebuild?

• WEB-INF/lib jars not found in JBoss 4.0.2 war deploy

  - by boongywoongy

  I have a simple web application (one jsp and one servlet) file that I've copied into jboss-4.0.2/server/default/deploy folder and it has successfully hot deployed as I can access the jsp page. However, when I invoke the servlet, I am getting a java.lan.NoClassDefFoundError. I suspect that the jars under the WEB-INF/lib directory within the war is not being picked up. The structure of my war is: META-INF --> MANIFEST.MF WEB-INF --> classes --> ...*.classes --> lib --> jcommon-1.0.16.jar jfreechart-1.0.13.jar servlet-api.jar index.jsp Anybody else have classloading issues in JBoss 4? Many thanks.

• django sphinx automodule -- basics

  - by haras.pl

  Hi, I have a projects with several large apps and where settings and apps files are split. directory structure goes something like that: project_name __init__.py apps __init__.py app1 app2 3rdparty __init__.py lib1 lib2 settings __init__.py installed_apps.py path.py templates.py locale.py ... urls.py every app is like that __init__.py admin __init__.py file1.py file2.py models __init__.py model1.py model2.py tests __init__.py test1.py test2.py views __init__.py view1.py view2.py urls.py how to use a sphinx to autogenerate documentation for that? I want something like that for each in settings module or INSTALLED_APPS (not starting with django.* or 3rdparty.*) give me a auto documentation output based on docstring and autogen documentation and run tests before git commit btw. I tried doing .rst files by hand with .. automodule:: module_name :members: but is sucks for such a big project, and it does not works for settings Is there an autogen method or something? I am not tied to sphinx, is there a better solution for my problem?

• How can I prevent IIS from trying to load a dll?

  - by Abtin Forouzandeh

  My project is a Speech Server application using Windows Workflow. It runs as an app under IIS. It supports a plug-in system. Here is what is happening: Load DLL into memory and set the type on an InvokeWorkflow control. When the InvokeWorkflow control runs, it appears to correctly instantiate the workflow from the loaded assembly - it completes the Initialize method. Everything crashes an burns, the target workflow is never executed. I can resolve this by putting a copy of the DLL in the application's executing directory. The workflow then executes correctly So it appears that IIS is trying to reload the assembly, even though its already in memory. Is there anyway to alter or disable this behavior in IIS? Perhaps a hook I can write that will intercept the request to load the dll and use my own logic to do so?

• How can I use aliased commands with xargs?

  - by Nathan Fellman

  I have the following alias in my .aliases: alias gi grep -i and I want to look for foo case-insensitively in all the files that have the string bar in their name: find -name \*bar\* | xargs gi foo This is what I get: xargs: gi: No such file or directory Is there any way to use aliases in xargs, or do I have to use the full version: find -name \*bar\* | xargs grep -i foo Note: This is a simple example. Besides gi I have some pretty complicated aliases that I can't expand manually so easily. Edit: I used tcsh, so please specify if an answer is shell-specific.

• ShoutCast over SSL

  - by Honus Wagner

  So I've gone ahead and set up my ShoutCast server DNAS and set my DSP in Winamp on my host computer. The server listens on port 8000, so per some instructions I installed an output plugin for winamp (Shoutcast DSP) and used 8000 and the password to connect. Server accepts the connection. Now, what the heck do I do now? My host computer is SSL secured and the DNAS server is installed within the secure web directory (if that matters). My desired end result is that I want to listen to my ShoutCast setup at home (host computer) from any computer. I try browsing to my ip address and port 8000 (without using HTTPS) and it comes back with nothing. If I browse with HTTPS://my.server.com:8000, I get Error code: ssl_error_rx_record_too_long) Have I completely missed something, or am I just a total moron? Thanks.

• How do I generate coverage xml report for a single package?

  - by Wraith

  I'm using nose and coverage to generate coverage reports. I only have one package right now, ae, so I specify to only cover that: nosetests -w tests/unit --with-xunit --with-coverage --cover-package=ae And here are the results, which look good: Name Stmts Exec Cover Missing ---------------------------------------------- ae 1 1 100% ae.util 253 224 88% 39, 63-65, 284, 287, 362, 406 ---------------------------------------------- TOTAL 263 234 88% ---------------------------------------------------------------------- Ran 68 tests in 5.292s However when I run coverage xml, coverage pulls in more packages than necessary, including python email and logging packages which have nothing to do with my code. If I run coverage xml ae, I get this error: No source for code: '/home/wraith/dev/projects/trimurti/src/ae': [Errno 21] Is a directory: '/home/wraith/dev/projects/trimurti/src/ae' Is there a way to generate the XML for just the ae package?

• Do different versions of Perl require different CPAN module installations?

  - by Leonard

  We have a server farm that we are slowly migrating to a new version of Perl (5.12.1). We are currently running 5.8.5. The OS will be upgraded from RedHat 4 to RedHat 5 as well, but RedHat 5 is still back on Perl 5.8.8. Thus for a while in our source tree we'll be supporting two versions of Perl. I have been told to install the new version of Perl into our source tree, and also all of the CPAN modules we currently use. I was actualy told to 'compile' the modules with the correct version of Perl. I'm confused by this. Do some modules actually configure themselves differently for different versions of Perl? Given this, I assume I should configure a CPAN directory for each version of Perl in our tree? Any information or 'gotchas' about this scenario?

• java "File not found" when using commons-configuration XMLConfiguration with Tomcat

  - by Bruno Shine

  Hi all, I'm building two apps that uses commons-configuration XMLConfiguration. Since the apps are related, I've build another project, called commons, that has a custom configuration manager that initializes the XMLConfiguration like so: config = new XMLConfiguration("conf/config.xml"); What happens is that the "command-line" app works fine, loading the configuration file. But when I try to use my custom configuration manager on a webapp (using tomcat) I get a "org.apache.commons.configuration.ConfigurationException: Cannot locate configuration source". I've placed the conf directory on the WEB-INF folder, the root folder and the META-INF folder. I've also tried with "/conf/config.xml", "./conf/config.xml" and "../conf/config.xml". The only time I got this to work - on the web app - was using a absolute path. What am I missing? Thanks, Bruno

• how do I use svn in eclipse?

  - by firesoul453

  I'm trying to create my own SVN server so I can work on my android projects everywhere. I have an VPS and I installed svn, I set up the directory and added a use to the password file. After a while I finally managed to create a project with svn import -m "initial import" . file:///home/admin/svn/reposvn/testp/trunk But I don't understand? Can I only import project that are on my server? If thats the case I could just use ftp and not worry about svn at all. What I would like to do is have a url to use in things like eclipse. my subdomain points to /home/admin/svn/ and then I typed in /reposvn So I tried the urls http://(mydomain)/reposvn and svn://(mydomain)/reposvn but neither worked Says Detected a cycle while processing the operation svn: Redirected cycle detected for URL .... I also set up daemon or whatever with svnserve -d any ideas? Thanks!

• Separate log files for each web application and shared libraries with log4j

  - by oo_olo_oo

  I have few web applications run on the Tomcat server. Each application contains its own log4j library copy inside its own war. This allows for separate, flexible logging configuration per application. I also have few shared libraries (kept in Tomcat's shared libraries directory). I would like to have shared library loggers output among with the application (which uses them) loggers output (for example: if application A logs to file a.log, and uses library b.jar, I would like b.jar to log also to the a.log file). The problem is, that the shared libraries are loaded by the shared classloader, which causes that they can't access loggers defined by the applications. Is there any solution for this issue?

• Batch build using IAR tools

  - by Jim Tshr

  I am trying to do a batch build of a project using IAR tools. The processor is a CC2530, and it builds fine in the IDE. I have followed the documentation for batch build (Project/Batch Build) and created a .cspy file that is suppose to be my batch file, but in the comments in that file it indicates that I need a debug file (.ubrof) to execute with it. I can't find a .ubrof file and I have searched the whole project directory structure. Also, I want my batch build to build a production version without the debugging information. Where do I get a .ubrof file? How do I do a production batch build using IAR tools?

• Create and access folder outside Apache Tomcat webapps folder

  - by Padur

  My web application requires functionality where end users can upload content, that can be later downloaded or viewed by others, the problem with current scheme is If I create such folder as part of your web project under webapps, every time I do deploy your web application (*.war), the content of that directory will be lost (or overridden). I think the best way to accomplish that is to create folder outside of standard tomcat webapps and access it from there, not sure how to do. Please point in correct direction. I am using Tomcat 4.x soon will be moving to 6.x. -Padur
